Apparently Parsoid has always required this, and we've never sent it, yet somehow the code in production works. This may well be the cause of some of the selser issues we saw after the deployment attempt in January. Made oldid a required parameter in the API module, and default it to 0. When we get 0, we translate that to the empty string for Parsoid's benefit. We also need to explicitly get wgCurRevisionId in ViewPageTarget, and that's also 0 on new pages.
